Find Fibonacci series upto given levels

Fibonacci series is the series of numbers in which next number is the sum of previous two numbers. For example, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc. The first two numbers of Fibonacci series are 0 and 1.

In the given program, we will print the series upto the levels given by user. After giving 5 as a command line argument it will display only first five numbers in the series.

PROGRAM

class Fibonacci {

 public static void main(String[] args) {

  int a=0,b=1,temp,n;
  System.out.println("Fibonacci series upto given levels");
  System.out.println(a);
  System.out.println(b);
  n = Integer.parseInt(args[0]);
  
  n = n - 2;
  while(n > 0) {
   
   temp = a + b;
   a = b;
   b = temp;
   n--;
   System.out.println(temp);
  }
 }
}
